* Add support for RISC-V CORE-V extension (XCvBitmanip) with version 1.0.
-* The scrubber (pre-processor) now leaves in place more whitespace, to permit
- various constructs not fitting the basic "insn opnd1,opnd2[,...]" scheme to
- work. This, however, means that macro invocations like "m 1 + 2", i.e. not
- using double quotes or parentheses around the (apparently) sole argument,
- will now be treated as passing three arguments. Such lack of quotation /
- parenthesization was never reliable to use.

Changes in 2.43:
* Add support for LoongArch .option for fine-grained control of assembly
